Summary of change:
'''Audi 5 cyl (firing order 1,2,4,5,3)''' '''Trigger''' c010 HALL / HALL * primtrig HALL 5 pulse on crank * sectrig HALL 1 pulse on cam ---- '''Outputs (v3/20216 6 IGBT + 2 logiclevel; low voltage flyback on EC36/6) ''' (replacement of v3/375 8 IGBT). Will need another replacement, after v3/20216 damaged after igncoil test. Will need 2nd RS232 and BT-RS232. '''important: Ignition''' * old: M & W from IGBT outputs * '''new: TFSI: logiclevel output for active coils''' ** '''Use: 4 stepper outputs + 1 logiclevel ignout''' ** eg. EC18/4,5,10,11 and EC36/11 '''Ignition outputs. IGBT outputs, for old install. BAD choice for active coils, see above ! ''' See GenBoard/Manual/IgnitionOutput Ign 1cyl EC18-pin4 Ign 2cyl EC18 pin5 Ign 3cyl EC18 pin10 Ign 4cyl EC18-pin11 Ign 5cyl EC36-pin11 Hint: connect one output first, and test from VemsTune (ignition output testing). Make sure not to blow coils with misconfiguration (accidentally configuring as other output, activating output continuously) ---- '''Injector outputs'''. Order is weird (not in firing order) inj cyl1, EC36-pin7, INJ-A inj cyl2, EC36-pin20, INJ-D inj cyl3, EC36-pin9, INJ-E inj cyl4, EC36-pin19, INJ-B inj cyl5, EC36-pin8, INJ-C '''Inj+ EC36-pin23 flyback: good''' ---- '''Inputs''' TPS EC36-pin 1 TPS supply EC36-pin 29 TPS pin 1 ground Sec trigger HALL pin1 EC36-pin13 Pri trigger HALL pin1 EC36-pin 27 EC36-pin 28sec-pri trigger pin2 +5v Sec-Pri trigger pin3 ground IAT EC36-pin2 IAT 2pin ground CLT EC36-pin 14 CLT 2pin ground ---- '''Other outputs''' '''NOT USED: ALS EC36-pin 16 (p259/1) ... NOT connected''' * solenoid connected to p259/1 might cause damage * detail (resistance, max current ??) if in use, rethink * '''prefer a free injector output (or ignition IGBT output)''' ---- '''RPM actuator output EC36-pin17 (inj-H)''' * inj output should be safe, but is this shiftlight ? * yes, '''shiftlight: NOT connected''' * or variable intake solenoid ? * what exactly ? Measured resistance ? ---- '''fuel pump relay EC36-pin15''' * '''prefer a free injector output''' (or ignition IGBT output, or stepper output), p259 only as a last chance ** '''PLEASE change to a free injector output''' ---- WBO2 EC18-pin 7,13,18,9 WBO2 +12v 5A fuse ---- * EC36 pin '''5,21,22,26,32 ground''' * EC36-pin 25 vems supply +12v (5A fuse) ---- See * FileArea * GenBoard/Manual/IgnitionOutput * GenBoard/Manual/DigitalOut/Table * VemsTuneVersion '''See Validate feature !''' Ignition outputs modified to '''ec18 pin 4,5,10,11 and ec36 pin 11''' * sparks on test, but no injector output activation (not even in test mode). ** is failsafe mode somehow triggered ? ** +12V is present Injection SOLVED ! Igncoil part nr: 07K 905 715F Engine was running ! 2020-06-10, while ignition ON: * '''ECU fuse was blown''' ** Via telephone, the '''fuse blown during ignition/spark testing !''' (very important information !) ** See below ! * Since than '''fuse is blown after each ignition ON attempt''', even if only ECU is connected... ** all sensors disconnected ** sensors should not matter much, but outputs also disconnected, assumedly ? * 2020-06-2x '''stepper was blown (really), replaced; mcp3208''' was also damaged, replaced. ECU + engine was running. * 2020-07-11 worked quite well for appr. 8hours * trailer 1 hour (engine off) * next morning: 2020-07-13 (or 14th) '''ECU 5A fuse blown''' * after that, v3/20216 repeatedly blows fuse. ** exact cause Not known ** will need 1A fuse if possible '''VAG active coil COP Igncoil 4 pin U shaped connector, Pinout:''' * pin1 +12v (via relay, but '''NO FUSE !!!''' ) * pin2 GND * pin3 ECU output (stepper or logiclevel ignout) * pin4 GND This seems to match pinout (from [https://shop.vems.hu/catalog/product_info.php?products_id=112 webshop] * but using fuses is mandatory. 1 fuse (5A) / channel for correct installs, * or a shared fuse (15A) for sloppy installs ---- '''During spark testing v3/20216, was the sparkplug grounded''' ? * Eg. touched to cylinder head (which was grounded) ? ** yes, all 5 sparkplugs were removed, and grounded to cyl head (according to the quick phone interview) ** note that it is very easy to make some mistake during this test ; ** do we know if '''all the 5 igncoils survived, or some got damaged ?''' [http://vems.hu/files/MembersPage/DigoAudiAan/ vemscfg config file] Reviewed digoaudiAAN.vemscfg : * config validate warns about partial fuelcut enabled ** but that should not cause issues during spark test; * I don't see any issues in config that should cause it (dwell configured 1ms, ign_dwellmap = 1). ** Dave's best guess would be: some wiring problem ---- Config: [http://www.vems.hu/filethingie.php?subdir=DigoAudiAan 2020.07.20.vemscfg] ----
